The pavement forming the subject-matter of this application comprises a body which aflords the desired rigidity, and for this purpose, stone, and generall-ybroken stone, will answer. The constituent portions of the hody of the pavement are held together by a binder, and it is preferred to use'a waterproof hinder, such as bitumen. The cohesion of the binder is weakened to such an extent that the compound may be used without heating, and, with this end in mind, the mixture may embody a volatile solvent for the binder, such as gasoline. The stone or the like, which constitutes the body, should be clean, in order that the binder may coat the stone, and, further, the binder should not be permitted to return too rapidly to its point of maximum adhesive strength, as Y the gasoline or the like evaporates. Eoal oil is an ingredient having both of the properties last-above called for. Lime ma be used to preserve the plasticity of the itumen content indefinite y.
